Metal sheet cutting off machine

Abstract

The invention discloses a metal sheet cutting off machine which comprises an automatic feeding component and a cutting off component, wherein the automatic feeding component is transmitted through a synchronous wheel synchronous belt by a servo motor, and a feeding rubber roll and a press roll are driven to precisely rotate according to the feeding length; metal sheet strips pressed between the feeding rubber roll and the press roll are precisely transported forwards under the guidance of a feeding guide component, so that the automatic feeding function of the cutting off machine is achieved; a motor provides powder for the cutting off component; under the transmission of a circle-arc tooth synchronous belt and a transmission shaft side circle-arc tooth synchronous wheel, an eccentric wheel on a transmission shaft is driven to rotate to perform eccentric motion, and a bearing drives and acts on a frame body; and finally, a cutter is driven to perform rectilinear motion up and down under the guidance function of the guide component, so that the metal sheet strips are cut off. According to the metal sheet cutting off machine, a plurality of metal sheet strips can be automatically fed and cut off at the same time, the working efficiency is high, the cutter is easy to mount, the length accuracy is high after cutting, and the fracture is neat.

Description

technical field [0001] The invention relates to a metal sheet cutting machine, which belongs to the technical field of metal material cutting machines. Background technique [0002] The metal cutting machine is mainly composed of feeding parts and cutting parts functionally. At present, there are basically two types of feeding mechanisms for metal cutting machines commonly used on the market. One is the reciprocating clamping feeding type, which uses a pneumatic linear reciprocating clamping device to drive the metal bar to achieve feeding. The other is the roller type, and the bar is fed by the intermittent movement of three rollers that are not in a straight line. At present, the cutting parts of metal cutting machines on the market often use the cutter to rotate to cut off the round bar or use the relative sliding shear structure to cut off a large piece of plate metal with a certain thickness. In this way, for an extremely thin strip metal sheet (such as the alloy moly...

Problems solved by technology

In this way, for an extremely thin strip metal sheet (such as the alloy molybdenum sheet in the anti-theft acoustic and magnetic label, the thickness is only 0.02mm, and the width is about 6mm), its weight per unit length is not only much lighter than the metal bar, but also more durable. It has strong flexibility, so the clamping and roller feeding mechanisms commonly used in the market are not applicable, and the cutting parts of the general metal cutting machine are due to the gap between the cutting knife and the fixed knife. A certain movement gap makes it impossible for a general-purpose cutting machine to cut the above-mentioned extremely thin and tough metal sheets
